Why Get a Lightweight BCG?
As we mentioned above…lowering the mass of the principal thing moving effectually in your rifle is going to assist minimize the overall movement.
This will let you get back on target faster and reduce the felt recoil.
The normal communication is to use the full-car (FA) BCG compared to the lighter semi-car BCG when used in rifles where reliability is key.
And don't worry…full-machine BCG's are perfectly legal. It'southward the trigger grouping that makes something really full-car.
The extra mass of FA BCG's keeps things running smoothly in over-gassed AR-15's that were made to run a diverseness of ammo and in crappy environments.
Since y'all're looking at lightweight BCG's…you're probably messing around with a secondary AR-15…likely for competition.
Yous probably won't exist scrounging for ammo on the battlefield and so you can lower the corporeality of mass needed to make your rifle even so run 100%.
I know what you're thinking…
What about using the lighter semi-auto BCG?
Information technology'due south only slightly less weight at x oz and change compared to the FA of 11.5 oz…while the ones nosotros're going to talk about are getting down to the 5 oz range.
How Practice You lot Lower the Mass of BCG's?
Start…you tin cutting away "unnecessary" parts of the steel carrier.
And second…yous can apply more exotic materials that weigh less.
You'll see a mixture of these two types of mass lowering techniques in our roundup.
Speaking of which…let's become started!
Best Lightweight BCGs
Nosotros've tried out three of the most popular ones on the market…

Prices accurate at time of writing
- Weight: 8.9 oz
- Price: $335
- Material: Steel
- Notes: No serrations for utilise of the forward assist
JP was i of, if not the first, major visitor to sell lightweight BCGs. For a while, they stopped, just now they are back at it again with their Low Mass Operating Organization (LMOS) models.
Nosotros're at around the 1000 round count and don't see whatever major wearing…just sugariness low recoil shooting. It's made of steel then it should proceed on chugging.
Merely keep in heed that you'll lose the employ of your frontward assist office (who has ever actually used their forward assist though?).
*EDIT* I originally stated that this model was aluminum.
2. JP Enterprises Ultra Low Mass BCG
Lightest
437
at Brownells
Prices accurate at time of writing
Prices accurate at time of writing
- Weight: five.8 oz
- Price: $437
- Fabric: Aluminum
- Notes: Lightest BCG on the market today
This new BCG from JP recently came out and then nosotros haven't gotten our mitts on it yet…but we had to include it since information technology truly is ULTRA low mass.
Just with great weight reduction comes great price.
Both monetarily and reduced life. Because the BCG is the aforementioned fabric as your upper receiver (aluminum)…it will see some wear and degradation as it does its job…to a point where you accept to get a new one. For that reason, JP recommends that you lot utilize the Ultra merely in competition rifles.
It now has forward assistance capabilities, just later on a couple yard rounds you'll have to junk it for a new i.
3. Faxon Lightweight BCG
Virtually Affordable

From Faxon, maker of affordable and great barrels comes their lightweight steel BCG. Check out all of those weight reducing cuts!
Since it's steel…the carrier should last almost indefinitely like its semi and full-motorcar brethren.
We've been running information technology in our overall super lightweight build for around 800 rounds and it's been running polish as butter.
The price is right too at virtually $200 less than the normal JP aluminum BCG and even less weight. Merely good luck finding it in stock!

Since at the time of publication the Faxon was sold out everywhere…I'k throwing in JP's steel version for price-witting lightweight aficionados.
The weight is on par and you lot'll save if you scrounge up a bolt from a previous BCG.
five. Rubber City Armory (RCA) Titanium BCG
Thank you, titanium, for bringing the all-time of both worlds…the lightness of aluminum but the durability of steel.

I've been running the RCA for over a year (guess 2500 rounds) in my competition buildand I'k still non tired of tapers showing me the touching double-taps I become on targets.
half dozen. Brownells Lightweight BCG
A newcomer from Brownells which usually has great self-branded stuff. When you lot want to endeavor out going lightweight without breaking the banking concern.
Comes in three flavors of Nitride, Nickel Boron (my recommendation), or TiN (gold…yea you know who you are).

What Other Mods?
Since the AR-15 is a well-oiled motorcar where multiple parts have to work together…you can't just modify up thirty% of ane thing without having to mod others.
Here's what I found to have the best reliability combined with a lighter BCG.
JP Captured Spring
All-time Buffer Organisation
170
at Brownells
Prices authentic at fourth dimension of writing
Prices accurate at fourth dimension of writing
Gets rid of the *sproing* of the regular buffer tube spring…and makes your AR-15 feel and shoot SO much better. Especially needed since the standard buffer and leap are likewise heavy/stiff for your lightweight BCG.
Opt for the spring kit if you lot make up one's mind to get this road. I originally got the single pack and needed the lightest bound to go with my RCA BCG.
The kit lets you customize things to just how you like them.
Not ready to brand the jump to the entire organisation…check out a lighter buffer ($57) and tuned bound ($19).

Best Adjustable Gas Cake
Y'all'll really want an adjustable gas block since yous'll need less gas to move the lighter BCG. Otherwise, you'll accept a really fast moving BCG which might actually increase felt recoil and impairment parts.
My pick is for the Superlative Arms gas block (total review) since it has the drain off hole technology.
Conclusion
